Questions and Answers
- 1.
Plants need to move substances around their body just like us
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Plants need to move substances around their body just like us because they require nutrients and water for growth and survival. They have specialized tissues and structures such as xylem and phloem that transport these substances from one part of the plant to another. This movement of substances is essential for processes like photosynthesis, respiration, and the distribution of hormones and other signaling molecules. Therefore, it is true that plants need to move substances around their body just like humans do.Rate this question:

Which is made of dead cells?
- A.
Xylem
- B.
Phloem
Correct Answer
A. XylemExplanation
Xylem is made of dead cells. Xylem is a type of plant tissue that transports water and minerals from the roots to the rest of the plant. It is composed of long, hollow cells called tracheids and vessel elements, which are dead at maturity. These dead cells form a network of interconnected tubes that allow for the efficient movement of water and nutrients throughout the plant. Phloem, on the other hand, is a living tissue responsible for transporting sugars and other organic compounds from the leaves to the rest of the plant.Rate this question:

The Xylem is ______ and the phloem is _______. In general, the xylem is ________ and the phloem is ________
- A.
Green, yellow, outward, inward
- B.
Yellow, green, inward, outward
- C.
Green, yellow, inward, outward
- D.
Yellow, green, outward, inward
Correct Answer
C. Green, yellow, inward, outwardExplanation
In general, the xylem is green and the phloem is yellow. The xylem is responsible for transporting water and minerals from the roots to the rest of the plant, and it is located on the inside of the vascular bundle. On the other hand, the phloem is responsible for transporting sugars and other organic nutrients from the leaves to the rest of the plant, and it is located on the outside of the vascular bundle. Therefore, the xylem is inward and the phloem is outward in terms of their position within the vascular bundle.Rate this question:

Root hairs have a low volume to surface area ratio in order to obtain more water and minerals
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Root hairs have a low volume to surface area ratio because it allows them to have a larger surface area for absorption. This increased surface area enables the roots to efficiently absorb water and minerals from the soil, which are essential for the plant's growth and development. By having a low volume to surface area ratio, the root hairs maximize their ability to take up nutrients and support the overall health of the plant.Rate this question:

The process in which plants lose water vapor from the stomata is known as
Correct Answer
TranspirationExplanation
Transpiration is the correct answer because it is the process by which plants lose water vapor from their stomata. Stomata are small openings on the surface of leaves that allow for gas exchange, including the release of water vapor. Transpiration is an important process for plants as it helps to regulate their internal temperature, transport nutrients, and maintain turgidity.Rate this question:

Water and minerals move through the xylem from the roots to the top of the plant by
- A.
Diffusion
- B.
Osmosis
- C.
Pressure
- D.
Equilibrium
Correct Answer
B. OsmosisExplanation
Water and minerals move through the xylem from the roots to the top of the plant by osmosis. Osmosis is the process by which water molecules move from an area of lower solute concentration to an area of higher solute concentration through a semi-permeable membrane. In this case, the roots of the plant have a higher solute concentration compared to the top of the plant. Therefore, water moves from the roots to the top of the plant through the xylem vessels via osmosis to maintain equilibrium in solute concentration.Rate this question:

Water will move from a ____ concentrated region to a _____ concentrated region. It's like a magnet pulling water up the plant’s plumbing system
- A.
Low, high
- B.
High, low
Correct Answer
B. High, lowExplanation
Water will move from a high concentrated region to a low concentrated region. This is because water molecules tend to move from an area of higher concentration (where there are more water molecules) to an area of lower concentration (where there are fewer water molecules). This movement is similar to how a magnet pulls water up a plant's plumbing system.Rate this question:

Tick the gases that pass in and out of the stomata
- A.
Carbon monoxide
- B.
Carbon dioxide
- C.
Hydrogen
- D.
Water vapor
Correct Answer(s)
B. Carbon dioxide
D. Water vaporExplanation
Stomata are small openings on the surface of plant leaves that allow gases to enter and exit. Water vapor is released through stomata during transpiration, the process by which plants lose water vapor. Carbon dioxide is taken in through stomata during photosynthesis, where it is converted into glucose. Carbon monoxide and hydrogen are not gases that typically pass in and out of stomata.Rate this question:

- 9.
What are the cells called that surround the stomata?
Correct Answer(s)
Guard cells
Guard
Guard cellExplanation
Guard cells are the specialized cells that surround the stomata. They are responsible for controlling the opening and closing of the stomata, which allows for the exchange of gases and water vapor between the plant and its environment. The correct answer options all refer to the same type of cell, which is the guard cell.Rate this question:
